His teacher did not know that there was no such country, so the joke was a success.
The American student has prepared a presentation about the fictional country of Wakande from the comics of Marvel to the lesson of international marketing. He said that the country’s economy is based on the extraction of natural resources, such as fictional metal vibranium and referred to the civil war for the throne between T’Challa and Killmonger.
The teacher did not seem to know what Wakanda was, so she listened to the 11-minute lecture completely, asking clarifying questions. In the end she praised the student for her good work and soon found out that it was a joke.
